Experimental set-up and analysis (IMAGE)
Caption
Experimental set-up and analysis. Left: the robots scurrying around seen from above; the white dots indicate their direction of movement. Right: the particles are coloured according to their speed: fast (hot) particles are red, slow (cold) particles are blue. This experimental snapshot shows how a cluster of cold particles can coexist within an environment of hot particles. Below: a side view of the robots. (photo: HHU / Marco Musacchio)
